To classify what should be included in modern human behavior, it is necessary to define behaviors that are universal among living human groups. Some examples of these human universals are abstract thought, planning, trade, cooperative labor, body decoration, and the control and use of fire. Along with these traits, humans possess much reliance on social learning.^[12][13] This cumulative cultural change or cultural “ratchet” separates human culture from social learning in animals. As well, a reliance on social learning may be responsible in part for humans’ rapid adaptation to many environments outside of Africa. Since cultural universals are found in all cultures including some of the most isolated indigenous groups, these traits must have evolved or have been invented in Africa prior to the exodus.
